ESIM.DOG does not provide a true unlimited high‑speed eSIM for China.
The plans that carry the name “Unlimited” actually contain a fixed data cap such as 1 GB, 500 MB, 2 GB, 5 GB, or 10 GB for a day or a few days, and once the limit is reached the speed drops to 384 kbps (or 512 kbps for some 5G only plans).
ESIM.DOG offers fixed‑data plans that may suit heavier users. For example, a 50 GB plan for 30 days costs $21.19, a 20 GB plan for 30 days costs $10.74, and a 10 GB plan for one day costs $6.99, all with full 4G/5G coverage across China. These plans give a larger high‑speed allowance and may be more cost effective for travelers who need substantial data.
